Description

Technical Field

[0001] This utility model relates to the field of concrete pouring conduit technology, and in particular to a fixing device for an underwater concrete pouring conduit. Background Technology

[0002] Underwater concrete refers to concrete that is poured and hardened directly in water (such as rivers, lakes, oceans, etc.). Special measures must be taken during its construction to ensure that the concrete is not washed away or dispersed by water flow in the underwater environment and can maintain sufficient strength and durability.

[0003] To ensure successful underwater concrete pouring and maintain quality, a tremie pipe method is typically used, where the tremie pipe is directly inserted into the pile foundation hole. The securing of the tremie pipe is a crucial step in ensuring pouring quality. The securing method must guarantee the stability, verticality, and adjustability of the tremie pipe. Therefore, this paper proposes a securing device for underwater concrete pouring tremie pipes to ensure their stability. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fixing device for underwater concrete pouring pipes, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of the present invention provides a fixing device for an underwater concrete pouring conduit, including a support truss. A through hole is provided in the middle of the top of the support truss to facilitate the entry and exit of the conduit. A first electric hoist is installed on both sides of the top surface of the support truss, and a first steel wire rope is wound around the outer wall of both hoists. A fixing clip is installed at the bottom end of the two first steel wire ropes.

[0006] Four guide rails are installed on both sides of the inner wall of the supporting truss. A sliding mounting frame is slidably installed between the four adjacent guide rails. A guide frame is installed at the bottom of two sliding mounting frames. Multiple guide wheels are installed at the four corners of the inner wall of the guide frame. A guide tube body is installed between the multiple guide wheels, and its top end is engaged with a fixing clip.

[0007] The top of each of the four adjacent guide rails is mounted with a mounting plate. A second electric hoist is mounted on the top surface of each of the two mounting plates. A second steel wire rope is wound around the outer wall of each of the two second electric hoists. The bottom ends of the two second steel wire ropes are respectively fixedly connected to the top of the two guide frames.

[0008] Preferably, in any of the above schemes, the two bottom ends of the support truss are equipped with transverse supports, and the ends of the four supports that are far apart are bent downwards. The bottom ends of the four transverse supports are equipped with base plates. By using this scheme, it is easy to increase the size of the bottom end of the support truss, and the base plates can increase the contact area with the bottom surface, thereby improving the placement stability of the support truss and facilitating the guidance and limiting of the two sliding mounting brackets.

[0009] Preferably, in any of the above schemes, two symmetrically placed rollers are installed on the top surface of the support truss near the through hole. This scheme facilitates the guidance of the two first steel wire ropes, changes the direction of force transmission, and at the same time, the two rollers support the first steel wire ropes, leaving a certain distance between the two first steel wire ropes and the inner wall of the through hole, so as to avoid affecting the up and down movement of the first steel wire ropes.

[0010] Preferably, in any of the above schemes, the inner diameter of the through hole is larger than the outer diameter of the conduit body, and a gap is left between the inner wall of the through hole and the two first steel wire ropes. By using this scheme, it is easy for the conduit body to pass through the through hole. Since the inner diameter of the through hole is large, and it ensures that the fixing clip can pass through, it is convenient to place or remove the conduit body by hoisting equipment.

[0011] Preferably, the top of the outer wall of the catheter body is provided with four slots, and the outer wall of the fixing clip is threaded with four limiting bolts, with the ends of the four bolts respectively entering the interior of the four slots. This design makes it easy for the fixing clip to be clamped at the top of the catheter body by the four limiting bolts, and also makes it easy to unscrew the limiting bolts for disassembly later. The slots are designed to be through-hole as needed, so that the funnel can be clamped and fixed after the fixing clip and the funnel are installed.

[0012] Preferably, each of the above-mentioned solutions has multiple sliders installed on both sides of the two sliding mounting brackets. The multiple sliders are slidably connected to multiple guide rails. This solution facilitates the stable installation of the two sliding mounting brackets between four adjacent guide rails, guides the vertical movement of the two sliding mounting brackets, and has high matching accuracy and low friction, which facilitates the guidance of the sliding mounting brackets.

[0013] This utility model has the following advantages:

[0014] 1. The fixing device for an underwater concrete pouring duct is provided by setting up a support truss and eight guide rails. The eight guide rails are arranged in groups of four and are respectively installed on both sides of the inner wall of the support truss. The sliding mounting frame is slidably connected to the four guide rails. At the same time, a guide frame is installed between two sliding mounting frames, and multiple guide wheels are installed inside, which facilitates the limiting and guiding of the duct body. The top of the duct body is connected to two first steel wire ropes through a fixing clip. The duct body is driven to move vertically by two first electric hoists, which ensure the stability of the duct body movement. The overall structure is simple and reasonable, and it is easy to promote and use.

[0015] 2. The fixing device for an underwater concrete pouring duct is provided by setting a fixing clip with both ends protruding outward and fixedly connected to the bottom end of the first steel wire rope. This allows a certain space to be reserved at the top of the duct body, facilitating the installation position of the funnel and enabling the external concrete to be poured smoothly into the interior of the duct body. By setting eight guide rails, it is convenient to limit the two sliding mounting frames. By energizing two second electric hoists, it is convenient to drive the sliding mounting frames and guide frames to move vertically, meeting the construction needs of different occasions.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] like Figures 1 to 4As shown, a fixing device for an underwater concrete pouring pipe includes a support truss 1. A through hole 5 is provided in the middle of the top of the support truss 1 to facilitate the entry and exit of the pipe. A first electric hoist 3 is installed on both sides of the top surface of the support truss 1, and a first steel wire rope 6 is wound around the outer wall of both. A fixing clip 9 is installed at the bottom end of the two first steel wire ropes 6.

[0023] Four guide rails 13 are installed on both sides of the inner wall of the supporting truss 1. A sliding mounting bracket 12 is slidably installed between the four adjacent guide rails 13. A guide bracket 10 is installed at the bottom of the two sliding mounting brackets 12. Multiple guide wheels 11 are installed at the four corners of the inner wall of the guide bracket 10. A guide tube body 17 is installed between the multiple guide wheels 11, and its top end is engaged with the fixing clip 9.

[0024] The top of each of the four adjacent guide rails 13 is mounted with a mounting plate 8. The top surface of each of the two mounting plates 8 is mounted with a second electric hoist 7. The outer walls of the two second electric hoists 7 are wound with second steel wire ropes 18. The bottom ends of the two second steel wire ropes 18 are fixedly connected to the top of the two guide frames 10 respectively.

[0025] The supporting truss 1 is welded together using structural steel, which facilitates its processing and manufacturing. It provides high mechanical strength and, being made of structural steel, is lightweight yet strong, has a large span, good rigidity, and is easy to construct, thus resisting vertical loads. It also provides an installation position for the guide rail 13, ensuring its vertical installation and guiding the sliding mounting bracket 12, facilitating later adjustment of the placement height of the two sliding mounting brackets 12 and the guide bracket 10.

[0026] Both bottom ends of the supporting truss 1 are equipped with transverse supports, and the ends of the four supports that are far apart bend downwards. The bottom ends of the four transverse supports are equipped with base plates 2. As an optional technical solution of this utility model, this makes it easier to increase the size of the bottom end of the supporting truss 1. The base plate 2 makes it easier to increase the contact area with the bottom surface, thereby improving the placement stability of the supporting truss 1 and making it easier to guide and limit the two sliding mounting brackets 12.

[0027] Two symmetrically placed rollers 4 are installed on the top surface of the support truss 1 near the through hole 5. As an optional technical solution of this utility model, this facilitates the guidance of the two first steel wire ropes 6 and changes the direction of force transmission. At the same time, the two rollers 4 support the first steel wire ropes 6, so that there is a certain distance between the two first steel wire ropes 6 and the inner wall of the through hole 5, so as to avoid affecting the up and down movement of the first steel wire ropes 6.

[0028] The inner diameter of the through hole 5 is larger than the outer diameter of the conduit body 17. A gap is left between the inner wall of the through hole 5 and the two first steel wire ropes 6. As an optional technical solution of this utility model, this makes it easy for the conduit body 17 to pass through the through hole 5. Since the inner diameter of the through hole 5 is large, and it ensures that the fixing clip 9 can pass through, it is convenient to place or remove the conduit body 17 by hoisting equipment.

[0029] The top of the outer wall of the conduit body 17 is provided with four slots 16. The outer wall of the fixing clip 9 is threaded with four limiting bolts 15, and the ends of the four bolts are respectively inserted into the four slots 16. As an optional technical solution of this utility model, this makes it easy for the fixing clip 9 to be clamped at the top of the conduit body 17 by the four limiting bolts 15, and at the same time, it is easy to unscrew the limiting bolts 15 for disassembly later. The slots 16 are designed to be through-type as needed, so that the funnel can be clamped and fixed after the fixing clip 9 and the funnel are installed.

[0030] Multiple sliders 14 are fixedly installed on both sides of the two sliding mounting brackets 12. The sliders 14 are slidably connected to eight guide rails 13 respectively. As an optional technical solution of this utility model, the sliders 14 are fixedly installed at the corner positions of the sliding mounting brackets 12 by bolts, and the sliders 14 are slidably connected to the guide rails 13, which facilitates the vertical sliding of the sliding mounting brackets 12 along the guide rails 13. This makes it easy for the two sliding mounting brackets 12 to be stably installed between four adjacent guide rails 13, guiding the vertical movement of the two sliding mounting brackets 12. At the same time, the fitting accuracy is high and the friction is low, which facilitates the guidance of the sliding mounting brackets 12.

[0031] The following steps are required when using this underwater concrete pouring pipe fixing device:

[0032] 1) When in use, the assembly of the guide tube body 17 and the fixing clip 9 is hoisted and placed into the pile hole beforehand, and then the support truss 1 is hoisted and placed directly above the pile hole;

[0033] 2) Wrap the two first steel wire ropes 6 around the roller 4 respectively, and fix the bottom ends to the two ends of the fixing clip 9.

[0034] 3) Securely connect the bottom ends of the two second steel wire ropes 18 to the top ends of the two sliding mounting brackets 12;

[0035] 4) By energizing and operating the two first electric hoists 3 synchronously, the pipe body 17 is driven to move vertically;

[0036] 5) By energizing and operating the two second electric hoists 7 synchronously, the two sliding mounting frames 12 and the guide frame 10 are driven to move vertically, thereby facilitating the adjustment of the relative position of the guide frame 10.

[0037] In summary, during use, the supporting truss 1 and eight guide rails 13 are set up, with four guide rails 13 in a group and installed on both sides of the inner wall of the supporting crossbeam 1. The sliding mounting bracket 12 is slidably connected to the four guide rails 13, and a guide frame 10 is installed between two sliding mounting brackets 12, with multiple guide wheels 11 installed inside. This facilitates the limiting and guiding of the conduit body 17. The top of the conduit body 17 is connected to two first steel wire ropes 6 through a fixing clip 9. The two first electric hoists 3 are powered on and run, driving the conduit body 17 to move vertically, ensuring the conduit body... The stability of the movement of the body 17 is ensured by its simple and reasonable overall structure, which facilitates its widespread use. By setting a fixing clip 9 with both ends protruding outward and fixedly connected to the bottom end of the first steel wire rope 6, a certain space is reserved at the top of the pipe body 17 to provide an installation position for the funnel and to facilitate the smooth pouring of external concrete into the interior of the pipe body 17. By setting eight guide rails 13, it is easy to limit the two sliding mounting frames 12. By energizing two second electric hoists 7, it is easy to drive the sliding mounting frames 12 and the guide frame 10 to move vertically, meeting the construction needs of different occasions.
